Leaky Feeder Antennas Data Sheet

Cables & Cable Assemblies

Includes description, features, benefits, and technical specifications.

Overview

Improve in-flight connectivity to wireless networks.

In an age when being connected to the Internet means being connected to the wider world, we expect to have Internet access everywhere — including commercial airplanes, where passengers expect easy access to Internet servers, email and in-flight entertainment while airborne.

GORE Leaky Feeder Antennas keep passengers connected. Our antennas improve signal propagation while reducing the amount of hardware required on the plane. These antennas provide reliable connectivity to different wireless systems, including picocells for mobile phone coverage and access points for airborne Wi-Fi.

Ideal for both wide-body and single-aisle passenger aircrafts, Gore's antennas significantly reduce dead spots, enabling passengers to connect to wireless networks throughout the cabin.

The inherently flame-retardant materials used in the construction of GORE Leaky Feeder Antennas meet the flame and smoke toxicity specifications of FAR Part 25.1359(d) and Airbus ABD0031 without added flame retardants.

Durable Construction

The engineered fluoropolymers used in the construction of GORE Leaky Feeder Antennas are inherently flame-retardant. They meet Airbus ABD0031 and FAR Part 25.1359(d) specifications for flame and smoke toxicity, which ensures reliable flame protection. These materials are also resistant to abrasion and cut-through, reducing the potential for damage during installation.

Reduced Costs for Wireless Access

Broadband technology used in aircraft generally requires separate equipment for each wireless protocol. GORE Leaky Feeder Antennas enable integrated hardware to run multiple protocols through a single antenna, reducing the quantity of wireless-N access points (N-WAPs) required to ensure signal coverage.

These lightweight antennas reduce equipment costs by offering a single solution that provides connectivity for a variety of electronic devices. Because of their durable construction, our Leaky Feeder Antennas don’t require any maintenance for the life of the aircraft, and this further reduces operating costs.

Features & Benefits

GORE™ Leaky Feeder Antennas

GORE Leaky Feeder Antennas are engineered to be superiorly reliable during flights and over time. Enabling this reliability are features like:

  • uniform signal propagation for wireless access throughout the entire cabin
  • reliable access across a broad range of frequencies with a single antenna
  • reduced costs with single hardware set and cables that require no maintenance for the lifetime of the aircraft
  • outstanding flame and smoke protection with inherently flame-retardant materials
  • easy installation for new production and retrofit applications in both single-aisle and wide-body aircraft
  • increased flexibility with rugged cut-resistant and abrasion-resistant construction
  • reduced exposure to wireless radiation

With a single antenna installed along the length of the cabin, passengers can access wireless networks for their laptops, tablets, mobile phones and in-flight entertainment systems regardless of their location in the cabin.

These antennas dramatically reduce dead spots because of the proprietary technology that maintains excellent antenna gain and coupling loss over a broad range of frequencies and antenna lengths as measured according to IEC 61196-4, Free Space Method.

Applications

GORE Leaky Feeder Antennas are typically used in:

  • wide-body aircraft
  • single-aisle aircraft
  • picocells for mobile phone coverage
  • Wi-Fi 802.11 a/b/g/n/ac and WiMAX

Additionally, the antennas commonly support connectivity to Bluetooth, DECT, DECT2, Globalstar, GSM, IRIDIUM Sat, MMS, PDC and TETRA protocols.

Proven Performance

GORE Leaky Feeder Antennas maintains excellent antenna gain and coupling loss over a broad range of frequencies and antenna lengths as measured according to IEC 61196-4, Free Space Method.
